[WIP] bpo-1294959: Better support for systems with /usr/lib64 by stratakis · Pull Request #11755 · python/cpython

This introduces a new configure and sysconfig variable `platsubdir`,
which is the name of subdirectory of $prefix that holds
platform-specific libraries. On many Linux distributions, there is
separation between /usr/lib and /usr/lib64, which was causing some
problems due to the way Python manages its install paths. Now, platsubdir
is used to select the appropriate lib directory.
